Assumptions

1. Single droplet in quiescent atmosphere.
2. Droplet temperature is uniform.
3. Density of liquid fuel much higher than the gas phase.
4. Fuel is a single component with no solubility for gases.
5. Flow velocities are assumed to be low
6. Single step irreversible reaction! Thin flame approximation.
7. Constant thermo-physical properties.
8. Unity Lewis number.
9. Radiation heat transfer is neglected.
10. No other phase is formed in the liquid fuel droplet.
